Boiler Replacement: Upgrade to an Energy-Efficient Heating System

Heating and hot water account for a significant portion of household energy use. Replacing an old or inefficient boiler with a modern condensing boiler can dramatically improve your home’s energy efficiency and lower your monthly bills.
Whether your current system is outdated, underperforming, or costing too much to run, free boiler replacement grants may be available to help you make the switch at no cost.

Why Replace Your Boiler?

Modern boilers, especially condensing models, are designed to reclaim and reuse heat from flue gases, achieving far better efficiency than older units. Here’s how upgrading can benefit you:

  •  Lower Energy Bills – New boilers waste less heat and use less fuel.
  • Improved Efficiency – Modern condensing boilers exceed 90% efficiency.
  • Greater Reliability – Reduce breakdowns and costly repairs.
  •  Reduced Carbon Emissions – Help meet UK climate goals with an eco-friendly system.

More Consistent Heating – Enjoy a warmer, more comfortable home.

Free Boiler Replacement – Are You Eligible?

You may qualify for a free boiler replacement under government-funded schemes like ECO4 or GBIS if:

  • You have a non-condensing boiler currently installed.

  • You have a condensing boiler over 10 years old with an efficiency rating of 85% or lower.

How to Identify a Condensing Boiler

Not sure what type of boiler you have? Use the following clues:

  • Plastic Flue: A plastic flue usually indicates a condensing boiler. Metal flues suggest a non-condensing model.

  • Plastic Condensate Pipe: A visible plastic pipe exiting from the bottom of the boiler to a drain is a key sign.

  • Installation Date:

    • Gas/LPG Boilers: Installed after 2005? Likely condensing.

    • Oil Boilers: Installed after 2007? Likely condensing.

If you’re unsure, our professional surveyors can assess your system and confirm eligibility.

Replacing Your Boiler – What to Consider

  • When replacing your boiler, it’s important to evaluate:

    •  Boiler Type: Combi, system, or regular—each suits different property sizes and water usage patterns.

    • Installation Cost: Grant schemes may reduce or eliminate installation costs entirely.

    • Energy Efficiency: Upgrading to a high-efficiency model ensures long-term savings.

    • Performance & Reliability: Modern boilers come with advanced features, better warranties, and smart heating controls.

    We make the process simple—from initial assessment to final installation.

Boiler Replacement FAQs

What is a condensing boiler?

A condensing boiler captures heat from flue gases that would otherwise be lost and uses it to improve heating efficiency—typically reaching over 90%.

If your boiler is over 10 years old, breaks down frequently, or is not condensing, it’s worth considering a replacement—especially if you’re eligible for a free upgrade.

Yes, landlords may be eligible if the tenant meets income or vulnerability criteria under the current grant schemes.
